LNT1K104MSEN

The LNT1K104MSEN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series designed for high-capacitance DC energy storage. This polarized, radial can package delivers 100000 µF at a rated voltage of 80 V and is intended for general-purpose power applications requiring large bulk capacitance and high ripple handling.

Engineered for robust operation up to 105°C with a rated lifetime of 2000 hours at that temperature (per the LNT series endurance conditions), this unit is suited for power-supply smoothing, buffering and other heavy-duty DC applications where high capacitance and reliable ripple performance are required.

Key Features

• High Capacitance — 100000 µF (100 mF) provides substantial energy storage for smoothing, hold-up and bulk decoupling in DC power systems.
• Rated Voltage — 80 V rating for mid-voltage power rails and industrial DC bus applications.
• Screw Terminal Mounting — Radial can with screw terminals enables secure, low-resistance connections for high-current applications and easy installation in rack or chassis assemblies.
• High Ripple Current Capability — 18600 mA at 120 Hz (low frequency) and 21390 mA at 100 kHz (high frequency) to support heavy AC ripple and switching-power loads.
• Thermal and Lifetime Performance — Rated for operation from −40°C to +105°C with a rated life of 2000 hours at 105°C under specified ripple/load conditions (per LNT series specifications).
• Leakage and Loss Characteristics — Specified leakage current of 5000 µA and a tangent of loss angle (tan δ) up to 0.4, enabling designers to account for standby losses and dissipation.
• Rugged Can Dimensions — Package dimensions φ90 × 170L (approx. 9 cm diameter × 17 cm length) for predictable mechanical integration and mounting.
• Regulatory Status — RoHS compliant, consistent with modern environmental requirements.
• Packaging for Production — Supplied in cardboard packing and listed as mass production to support volume manufacturing needs.

Typical Applications

• Power Supply Hold‑Up and Smoothing — Large bulk capacitance and high ripple current capability make the part suitable for DC power-supply smoothing and energy hold-up during transient loads.
• Industrial DC Bus Filtering — Screw-terminal mounting and robust ripple handling support use on industrial converters and bus-capacitor banks.
• Motor Drive and Inverter Support — Bulk energy storage and high-frequency ripple endurance help stabilize DC link voltages in motor drives and inverters.
• Energy Buffering — High capacitance for buffering energy in systems that require temporary energy storage during load changes or supply interruptions.

Unique Advantages

• Large Energy Density: 100000 µF at 80 V provides significant stored energy in a single component, reducing the need for parallel arrays.
• High Ripple Endurance: Specified ripple currents at both low and high frequencies let designers size capacitors based on actual switching and mains ripple conditions.
• Mechanical Reliability: Screw-terminal radial can with defined dimensions (φ90 × 170L) and mounting options simplifies secure installation in chassis and modular assemblies.
• Wide Temperature Range: −40°C to +105°C operation supports deployment across varied thermal environments while maintaining rated lifetime expectations.
• Production-Ready Packaging: Cardboard packing and mass-production availability support procurement and assembly at scale.
